WOVEN BODY FOR STEAM PAGKlNG.

SPEGIFICATION forming part of Letters Patent No. 567,970, dated September 8, 1896.

Application filed May 19, 1896. Serial No. 692,119. .No model.)

To all whom/ it may concern:

Be it known that I, J osEPH; HAWKRIDGE, a subject of Her Majesty the Queen of Great Britaimresid'ing at Sydeuhamlond'omcounty of Kent, England, have invented a new and useful Woven Body for Steam -Packing and Like Purposes, of which the following is a specification. v

This invention; relates to packing for steam and other joints and for other purposes, comprising a body woven of metal and asbestos strands and coated on its faces with waterproof or protecting material. v g

It is the object of my invention to provide for such packing an improved strong and durable body in which the asbestos strands are prevented from slipping in respect to the metal strands and to each other, in which all the strands are thoroughly consolidated. or

.closely placed or packedtogether, and in which the asbestos strands, while clinging firmly to place, present their fibers advantapacking having a portion ofthe rubber coat geously for felting or matting at the faces of the body, whereby the body is adapted to advantageously receive, retain, and present in use smooth coatings of waterproof or protecting material, as rubber. orother gum.

My invention consists of the improvements hereinafter described and-claimed.

The nature, characteristic features,- and scope of my invention will be more fully un derstood from the following description, taken in connection with the accompanying drawings, forming part hereof, and in which Figure 1 is a top or plan view of a piece of ing removed and showing a' body embodying features of my invention. Fig. 2 is a sectional view of the same taken in the direction of the warps. Fig. 3 is a view drawn to an exaggerated scale and illustrating one of the wire strandstwisted into spiral .form and one of the asbestos? strands twisted and spun around the spiral Wire. Fig. l is a similar view showing two compo nd strands like the one shown in Fig. 3 twi ted together, and

Fig. 5,."is' a diagrammatic View hereinafter referred to.

Ill the drawings, .1, Figs. 1 and :2, is the bod y woven of compound metal and asbestos thread. are coatings of watcrpro'otor protecizngi uatcrial, as rubber or the line;-

The threads 2 consist of metal strands 4,spun or twisted into Spirals, and of asbestos strands 5, as'shown- Such threads may be made from a straight wire 6 and an asbestos sliver 7, Fig. 3. In an asbestos sliver the fibers are disposed parallel to each other as. they are when they come from the carding-engine.-

'lhestrai'ght wire 6 and the asbestos sliver 7 Fig. 3. By these means the twisted asbestos sliver is caused to cling and is prevented from slipping in respect to the spiral wire,

and comparatively small compound threads may be produced adapted to be manufactured into a thoroughly consolidated fabric. More over, the twisted or spun sliver presents its outermost fibers; so that' they project by reason of their tendency to untwist, and these fibers may be readily matted or felted, as indicated at the left-hand side of Fig. 1, prior to the coating of the fabric. 4 compound strands like that shown in Fig-"3 If desired, two/8o may be twisted together, as shown in Fig. 4,

and then incorporated in, the fabric.

Having thus described the nature and ob jects of my present invention, what I claim'as new, and desire to secure by Letters Patent,

An improved body for steam-packing and like purposes comprisedof threads in which the metal strands aresp un or twisted into spirals and in which asbestos slivers are twisted or spunto spirally wind their fibers aronndztheni and are also spun or twisted around the metal spirals, whereby slipping, of the asbestos is opposed in each thread and consolidation and coating of the body are facilitated, substantially as described! In testimony whereof I have hereunto Signed-my name. 1

JOSEPH HAWKRIDGE.
